4028 Series
Bird’s® 4028 Series Power Sensors are a family of high accuracy sensors for use in high power LCD, TFT
and Solar processing and other precision high power applications. Intended for use with the industry
standard Bird Precision Laboratory Power Meter Model 4421, these products can provide a threefold
improvement in long-term unit-to-unit accuracy.
- Achieve tighter, more consistent RF power measurements for improved yield.
- ±2% accuracy at specified calibration frequencies and power levels.
- Direct, plug-in operation with the industry standard Bird Model 4421 RF Power Meter.
- Multiple sensors provide for measurement of 1 kW to 25 kW over a 250 kHz to 30 MHz frequency range.
PROBLEMS } SOLUTIONS
Very high power RF measurements required
} Measures power levels up to 50kW
Need very high degree of accuracy
} Capable of 2% accuracy
Require custom connectors
} 4028A Series sensor can be configured with a wide range
of connectors.
APPLICATIONS
Periodically, power delivery systems used in high power LCD,
TTA and Solar processes, as well as other precision applications,
must be calibrated against an accurate RF power standard.
This calibration is used to correct for any drift that may occur
in the system. Integrating a 4028 Series Power sensor in your
calibration process may improve accuracy and long-term
repeatability that can yield significant improvements on your
process yields.
